When the brain's supply of oxygen is reduced or eliminated, damage can set in very quickly. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works ...

The brain has a high energy demand and reacts very sensitively to oxygen deficiency. Ludwig-Maximilians-Universitaet (LMU) in Munich neurobiologists have now succeeded for the first time in ...

When brain cells become more metabolically active, they consume more oxygen, making this gradient steeper. Thus, this gradient carries information about how much oxygen is being consumed and can ...

While existing oxygen monitoring techniques provide information about a very small area of the brain, the researchers were able to observe, in real time, a large section of the cortex of the mice.

Your brain's a real oxygen hog. It's a small part of your body weight, but it uses 20% of your oxygen. It can't store the oxygen, so it needs a steady flow of blood to work well.

However, how much oxygen is consumed in the brain and how this is related to neuronal activity was so far largely unknown. LMU neurobiologists Hans Straka, Suzan Özugur and Lars Kunz have now ...

Brain oxygen levels are typically around 98%, and if they drop below 50%, a person is almost certain to lose consciousness, according to the statement.

MRI scans revealed significant brain injury. Her brain had started to shrink. She was losing both gray matter -- critical to muscle control, sensory perception and speech -- and white matter, the ...

The brain represents just 2% of body weight, yet it uses about 20% of the body's oxygen supply. To stream 13OYS on your phone, you need the 13OYS app. Download the 13OYS app ...

The brain requires a disproportionate amount of energy compared to its body mass. This energy is mainly generated by aerobic metabolic processes that consume considerable amounts of oxygen. Therefore, ...
